that was my next question. check the Auction profile field and tell me what Auction profile is selected.
So you must have deleted Auction profiles?
No worries. In the drop down menu in the auction profile field, select an appropriate Auction profile, then update. i.e. if these auctions are regular auction style, then select a profile that is regular auction and not an eBay store profile.
The Listing template field won't matter a bit for updating. That only affects Listing.
After you update, you can generate Invoices.
Let me know if that fixes the problem
